Relay Cycle Counts
The Agilent 3499A/B/C can read and track the relay cycle counts on some
plug-in modules. This feature can be very useful in switching systems to
track relay failures and predict system maintenance requirements.
•
This feature is supported in 3488 Mode by the Agilent N2260A,
N2261A, N2262A, N2264A, N2265A, N2266A, N2267A, N2268A,
N2270A, and N2280A/81A modules.
•
The cycle counts of the tree relays (s98 & s99) on an N2260A or
N2266A can also be queried.
